I hated Alex North because it made not a damn bit of sense in relation to established show cannon nor were their attempts to explain it adequately satisfactory. Meanwhile, it invalidated every. single. marriage. Marlena ever had on the show. Yes, Marlena had an affair with a married professor in her backstory (hell, the character even appeared on the show brief TWICE as a temporary wrench to Don/Marlena) but this story was nothing less than a hot mess.
